Specifies whether a custom action is a .NET Framework Installer class. A Installer class contains its own state management methods, allowing it to roll back an installation to its previous state.
This property should be set to true only for components that have been specifically configured as a Installer class. Simply changing this property does not turn a custom action into a Installer class.
The settings for the InstallerClass property are:
false
The custom action is not a .NET Framework Installer class.
true
The custom action is a .NET Framework Installer class.
When a custom action that has been configured as a Installer class is added in the Custom Actions Editor, this property defaults to true. For all other custom actions, this property defaults to false.
